Radioactive isotope radioactive isotope, also called radioisotope, any of several species of the same chemical element with different masses whose nuclei are unstable and dissipate excess energy … by spontaneously emitting radiation in the form of alpha, beta, and gamma rays. Every chemical element has one or more radioactive isotopes.For example, hydrogen, the lightest element, has three isotopes with mass numbers 1, 2, and 3. Only hydrogen-3 (tritium), however, is a radioactive isotope, the other two being stable. More than 1,000 radioactive isotopes of the various elements are known. radioactive isotope is a form of an element that is unstable and eventually decays into a different element. For example, most Carbon has 6 protons and 6 neutrons, and is st … able.

- an isotope is an atom that is heavier or lighter than a normal atom of the same element. the number of protons is different. for example, carbon usually has an atomic mass of … 12: 6 protons, 6 neutrons. but in carbon 14 (an isotope of carbon), there are 6 protons and 8 neutrons.

Chemistry for Kids Isotopes are atoms with the same number of protons and electrons, but a different number of neutrons. Sometimes isotopes are stable and happy. These are the elements that we see around us and find in nature. However, some isotopes are unstable.he half-life of an isotope is the time on average that it takes for half of the atoms in a sample to decay. For example, the half-life of carbon-14 is 5730 years. This means that if you have a sample of carbon-14 with 1,000 atoms, 500 of these atoms are expected to decay over the course of 5730 years.

Understanding and Applying Chelated Fertilizers Effectively Based on Soil pH 1 Chelation keeps a micronutrient from undesirable reactions in solution and soil. The chelated fertilizer improves the bioavailability of micronutrients such as Fe, Cu, Mn, and Zn, and in turn contributes to the productivity and profitability of commercial crop production.

The Three Isotopes of Hydrogen Because the number of neutrons are different, they also have different atomic masses, the total number of protons and neutrons combined. As an example, let's take a look at the isotopes of hydrogen. Hydrogen has three isotopes: hydrogen-1 (protium), hydrogen-2 (deuterium) and hydrogen-3 (tritium). In the following illustration, we can see subscripts and superscripts. The superscripts 1, 2 and 3 written before H are the atomic masses of the isotopes of hydrogen and the subscript 1 is the atomic number.

List of Radioactive Elements List of Radioactive Elements. A radioactive element is one with an unstable nucleus, which radiates alpha, beta or gamma radiation and gets converted to a stable element. This article has a comprehensive list of radioactive elements and their properties.alf-life is the amount of time required, for half quantity of radioactive element to decay. For example C 14 has a half life of 5730 years. That is, if you take 1 gm of C 14, then half of it will have been decayed in 5730 years. In the list presented below, half-lives of all the radioactive elements are presented.

- Radioactive elements produce some radiation in the form of neutrons and alpha and beta particles. Heavier elements such as uranium emit neutrons when they split to form lighter elements. Some radioactive substances emit alpha particles, which are helium nuclei -- two neutrons and two protons.

Atoms, Isotopes, Ions, and Molecules The nucleus is surrounded by electrons. The half-life of a radioactive isotope is the time taken for half its radioactive atoms to decay. There are three main types of radiation, called alpha, beta and gamma radiation, which all have different properties.Radiation can damage cells and make them cancerous.ll the atoms of a given element have the same number of protons and electrons. However, the number of neutrons can vary. Atoms of the same element that have different numbers of neutrons are called isotopes of that element.

How much space should I allow per person when building a kitchen island? I'd allow 24 inches per, so people can enjoy breakfast without banging elbows. A popular arrangement is to have seating on one side and both ends, if space allows. The overhang should be minimum 12 inches, 15 is better. Plan to allow 36 - 42 inches between the island and the nearby kitchen countertop. You want people to be able to safely pass (while carrying very hot items).

- Radioactive substances give out radiation all of the time. There are three types of nuclear radiation: alpha, beta and gamma. Alpha is the least penetrating, while gamma is the most penetrating. Nonetheless, all three are ionising radiation: they can knock electrons out of atoms and form charged particles. Radiation can be harmful, but it can also be useful - the uses of radiation include to: detect smoke.

CONTENTS Isotopes are atoms of a particular element with different numbers of neutrons. A radio isotope is an isotope that is radioactive because the nucleus is unstable. 1 person found this useful.Edit.aid another way, one element may exist in a number of different forms called isotopes. Each element has a number of different isotopes, and this is determined by the number of neutrons in the nucleus. Let's look at an example.

isotope An isotope is a form of a chemical element whose atomic nucleus contains a specific number of neutron s, in addition to the number of proton s that uniquely defines the element.The nuclei of most atom s contain neutrons as well as protons.n atom of carbon-14 contains 6 protons and 8 neutrons and is denoted 14 C. Over time, 14 C decays into 12 C. Sometimes the isotope of an element is denoted by writing the nucleon number after the chemical symbol, and not as a superscript.

Biology, Eighth Edition (Raven) Radioactive isotopes are versions of elements such as carbon, nitrogen, or phosphorus that unstable and release neutrons to become more stable isotopes. The radioactive signal given off by the emission of neutrons allows scientists to detect the isotopes even when they cannot be seen. Adding isotopes to biological systems allows scientists to trace both molecular pathways and the locations at which these pathways occur.

What makes some isotopes have an unstable nuclei and others not? For most of the element there are different isotopes, atoms with the same number of protons but different numbers of neutrons. For example, carbon atoms always have six protons, but may have six, seven, or eight neutrons. Some isotopes are stable, but others are radioactive. An isotope will be radioactive if its nuclei are unstable. Large atomic nuclei, with more than 93 protons and their associated complement of neutrons, are inherently unstable. Uranium and plutonium are examples of such elements.

What Are Some Ways That the Isotopes of an Element Differ From Each Other? Carbon also has a range of isotopes which include a 6-neutron, 7-neutron and 8-neutron isotope. These three carbon isotopes are called carbon-12, carbon-13 and carbon-14, respectively. The atomic mass of each of these isotopes is derived by adding the number of neutrons in each isotope to the number of protons. The atomic mass of carbon-14, for example, is 14, because 6 protons plus 8 neutrons equals an atomic mass of 14.
